I have no idea what all the different denominations hold for their doctrine or sacraments, but I have gone into the web, and printed out several from the mainstream Churches, and yes, I would imagine that of all the non catholic Christian Churches out there, 95% have the doctrine for salvation.

By inference, can I conclude that you would similarly maintain that on those various points of doctrine where they conflict, some are correct and possess the truth, and some are incorrect (by virtue of human fallibility/sin) and do not posses the truth, with relation to those particular points of doctrine that are not (in your opinion), essential for salvation?
